The frequency of posttraumatic stress disorder (PTSD) ranges from 10 to more than 50 percent in urban primary care settings where the prevalence of trauma is high. There is also growing evidence that PTSD is linked to chronic disease such as diabetes and heart disease, and with poorer health outcomes. In fact, a recent study found that PTSD was significantly associated with a hemoglobin A1c level (a marker of diabetes control) greater than seven percent among low-income minorities. The researchers recruited men and women with type 2 diabetes from four community-based primary care clinics in Harlem, New York City. In addition to demographic information, participants were screened for depressive symptoms and for lifetime PTSD. http://www.ahrq.gov/research/feb12/0212RA12.htm
